So these persons are all less than Sudras but Srimad-Bhagavatam says even they, under the guidance of a pure devotee, can also be raised up the the highest standard more than the Brahmanas. If somebody questions how it is possible, how the most degraded of the human society be more than a Brahmana that is also confirmed in Vedic language that it does not matter if one is born of low grade family or candalas, if he is a devotee of the Lord, he is first class man. There are other statements that a man after becoming a devotee becomes immediately qualified to execute sacrificial ceremonies. In this connection, Jiva Goswami has given his commentation that a person born even in a Brahmana family is dependent on the purificatory processes as accepting initiation and sacred thread, but a devotee without waiting for such recognition becomes fit to act as a Brahmana, and this is the statement of Narada Muni in this verse. This means as stated in the Bhagavad-gita there are different symptoms of different classes of men—just like a Brahmana is truthful, clean, self-controlled, equipoised, tolerant, simple, full of knowledge, theist, and so on. Similarly a Ksatriya has symptoms—a tendency for ruling over others, martial spirited, charitable, does not flee away from the battlefield and so on. Similarly, the symptoms of a Vaisya is his tendency to agriculture, trade, cow protection and banking. And the Sudra's tendency is to some way or other work anywhere and get some wages.
So Narada Muni says that these symptoms are not stereotyped or stagnant; they are flexible. A man may be born in the family of a Brahmana but he might have the tendency of a Ksatriya or Vaisya or Sudra. Similarly a man may be born in the family of a Sudra or Candala but he may have the tendencies for a Brahmana. Just like Ekalavya was born in a Candala family but he had the tendency of a Ksatriya. Similarly Visvamitra Muni was born in a family of Ksatriyas but his tendency was of becoming a Brahmana.
So Narada Muni says that men should be judged by his tendencies, not by his birth, and this is also confirmed in Bhagavad-gita by Lord Krishna that the four divisions of human society should be judged by the qualities in actual work. Therefore with reference to all Vedic Scriptures our members are all Brahmanas and therefore we offer them the sacred thread although they are born, according to Vedic culture, in the families of other than Brahmanas or even than the Sudras. But that does not mean they cannot be purified. Actually they are being trained in such a way, their hearts are being purified by chanting the Mahamantra. And after some days when the Spiritual Master sees that one has followed the regulative principles faithfully and has abstained himself from the restricted items like illicit sex life, etc. and has chanted regularly 16 rounds then say after a year or six months when he appears to be purified in the judgment of the Spiritual Master he is offered the sacred thread, and he is given the chance of Deity worship in the Temple. These Smarta Brahmanas contest that unless one is born in a Brahmana family one cannot be given these facilities. But Narada Muni says no; a man should be judged by the symptoms of his character. And Srimad-Bhagavatam says that the Kiratas, etc. can be purified by a pure devotee because the influence of Lord Visnu is so strong. Prabha Vishnave means the powerful Lord Visnu; prabha means that the light or heat of Visnu is so strong that it is possible to melt them. Only the devotees of Lord Visnu or Krishna can be purified, not the devotees of any demigod. They will have to wait for their next birth according to their own karma.
So under this formula the whole European and American people who are so intelligent and materially advanced can be converted into pure Vedic Brahmanas, and thus their mission of human life becomes successful, and the whole world becomes a garden of blooming flowers.
Take all these words very seriously and try to propagate Krishna Consciousness with all serenity. It will be a great gift to the human society. You are a learned and intelligent and young man; think over the formula and try to execute to the best of your capacity. That is my request.
